There are seven asteroidal objects reported within ten lunar distances (LD) of our home world today. Nearest is 2018 CH2, which is outbound from 2.11 to 3.27 LD as it passes the Moon by 2.38 LD at 0151 UTC and leaves Earth's sphere of gravitational influence.

This report was generated at 1816 UTC with first follow-up for outbound 2018 CB2 and departed intruder 2018 CS1 in today's DOU MPEC along with continuing follow-up for approaching 2017 VR12 and distant 208023 1999 AQ10.

Notes: Ten times the distance to the Moon (ten LD) has no astronomical importance but is a useful boundary for reporting about transient natural objects that approach our planet's gravitational sphere of influence (SOI), which has a radius of about 2.41 LD from Earth's center. This puts a focus on some of the most important and very best NEO observation work, representative of the much larger NEO discovery and tracking effort. "Distant" is used here to describe an object that has come within ten LD since A/CC began these traffic reports (2007) but is not presently so close. Object temporal distances are derived by A/CC from JPL Horizons data. See also current sky chart and object details (alt-details), ephemerides, and today's timeline.
